Abstract:
The purpose of the present invention is to reduce the tip clearance between a tooth tip and a tooth bottom. In this scroll fluid machine, the end plate of a fixed scroll is provided with an end plate inclined section (3a1) in which a tooth bottom surface facing a tooth tip of a wall body inclined section is inclined in accordance with the incline of the wall body inclined section. A contour line (Ct1) is formed in a direction orthogonal to the spiral direction of a wall body (3b) on the end plate inclined section (3a1). A wall body inclined connection section (5b5) to which the wall body inclined section and a wall body flat section are connected is arranged with the phase thereof delayed by a radius of rotation ρ with respect to an end plate inclined connection section (3a5) at which the end plate inclined section (3a1) and an end plate flat section (3a3) are connected.
